This study compares the stiffness of the single-pad and the double-pad aerostatic bearings with pocketed orifices. The stiffness comparison is based on the given loads, which provide useful information for bearing design. Bearing design parameters include supply pressure, pocket size, orifice design, and applied load. Therefore, the analysis of double-pad aerostatic bearings is complex because of the independent design of upper and lower bearings. Results show that a double-pad aerostatic bearing with the same upper and lower bearing is not the best design and that double-pad aerostatic bearings have higher stiffness than the single-pad aerostatic bearings.
